As the printingof consecutive numbersfor eachline is impracticable on account of the vspacee-required uponthe chart andlbecause of the difficulty of distinguishing them, I havedevised a peculiar consecutive register -which enables me to print aline for each line which; is cast. on the machine and a number:at;-every.tenth line.

which, I have employed. myinvention this 7 is an alternativeconstruction for the operating mechanism of the consecutive registers.Figs. 8 to 14 are details of the peculiar form of consecutive registeremployed. Fig. 15 is a plan of part of the apparatus, with some partsomitted.

I will describe first the general arrangement of the apparatus shown inFig. 1, afterward describing it more particu arly m in detail. -Upon therock-shaft A is secured the switch B by means of the plate A, fast tothe switch, and another plate A the two plates being connected by boltsa a which cause them to grip the shaft. Leads 0 0 pass 15 to a battery Gand an electro-magnet D, so that when the rock-shaft operates the switchthe circuit is momentarily closed and the eiectro-magnet is energized.When this occurs the armatures cl d, carried by the lever 24} D areattracted and the hook D is raises. momentarily, releasing the detent72. The cam H then drops upon the constantly revolving roller E, itbeing pivoted at h in the lever H which is pivoted at h the g. spring 7Lpresses down the lever so that the cam is firmly engaged by the rollerE. As the cam, which is eccentrically pivoted, rotates, it raises theright-hand end of the lever H and the left-hand end thereof forces 3{}down the consecutive register L against the ribbon K, so that printsupon the chart i, passing over the platen K The ribbon IQ is fed by themechanism shown in Fig. a, presently to be described, which is operatedby the eccentric F from the shaft of the constantly revolving roller E,the rod F pass-' ing from the eccentric to the ban F and causing the rodF to reciprocate. A number of these mechanisms is assembled as indicatedin Fig. 15, one, connected to each machine the work of which is to berecorded by the monitor.

In Fig. 1*, I show the switch B connected to the line-deliveryrock-shaft A of a linotype machine, the frame of which is indicated at Athe lever A is that of the linedelivery slide. It will be understoodthat the leads from the terminals 0 c of the switch pass to the batteryC and magnet D, as 5 shown in Fig. 1.

' At G is a clock-driven gear which operates the roller G which feedsthe ,paper, the latter being pressed against it by the pressure-rollerGt An idler G1 connects the 5- main gear of the clock to the pinion Gcarrying pins 9 g, cooperating with the escapement lever G: to operatethe time-printing mechanism, presently to be described. The operation ofthe clock is such that one or the other of these pins strikes the leverGr twelve times in the hour.

Referring now to Figs. 1, 2 and 3, I will describe the construction ofthe switch which I have devised. It is important that this i switchshall operate without sticking, be-

cause, as will be manifest from Fig. 1, if the switch should stick thelever 13 will be held down and the particular consecutive register whichit controls will be operated as often as its cam H revolves. Whiletherc- 7o fore I could employ many forms of switches, and any form willbe, so far as the general objects of my invention are concerned, anequivalent structure, I prefer the mercury switch shown, which operatesin the manner following: The switch is shown in side clevation in Fig.1, and is formed of any sui3table substance, though in en 'a to have itof insulating leads 0 c are properly iHSL to such a length that theypart of the channel, it is no the material of the switc channels B Bcross one nect at each end. A "Jule is poured into one of the c cover Bcarrying the leads 0 c I. on. When the switch is in the shown in Fig. I,the mercury Y into the position shown in d When the shaft A isreciprocateu cury will run down the channel i: switch is lowered by therotation. shaft in the direction shown by the arrow;

it will then run over into the low part of the channel 13 at the left inFig. 2, passing the low part b of the partition between the ,twochannels as shown in the upper part of Fig. 3, bridging the contacts a cas it does so. lVhen the shaft raises the switch, the mercury runs downthe channel B over the low spot 6 between the two channels, back to theillustrated position. The length of time of the contact may becontrolled to the desired extent by the amount of mercury which is usedto bridge the terminals and by the pitch of the channels B B but it willbe evident that with the construction indicated there can be nomaintenaz' :e of contact undesignedly, and that the a of the apparatuswill be such that fiy 5.8 time the detent 7L passes out end of the hookD (in Fig. l) the ircuit will have been opened, and the r 3.) ill. haveresumed its place in ti.. o catch the detent when it comes around to theillustrated position.

I will now describe the apparatus more particularly in connection withFigs. 1 and 15. Referring particularly to Fig. 15, it will be seen that.the time printing stamp T is arranged in line with the consecutiveregisters L L; I have only illustrated three of the latter, although thechart shown provides for ten, because the others are similar to thoseshown and because the selection of number is arbitrary, as will bereadily un- .derstood. In Fig. 15 the parts are as before; but theroller E, which is the main operating shaft of the device, is driven bya gear), on the shaft ofa motor P, which meshes with the pinion drivingthe roller it is preferable to ma a positive drive for this roller. Eachof the cams H, as shown,

is made in two parts, in a channel between which lies'the hook D 1, andthe lever H is also by preference a frame composed of side-bars unitedby rivets H, H H having spacing washers, thus making a rigidconstruction not liable to tilt sidewise under strain. The levels are.all journaled upon a common shaft k Inpractice the machine is made withone time-printing mechanism and as many as may be desired of theconsecutive registers, which are assembled as independent units. Thetime stamp, however, is operated independently of any of the registeringmechanisms. The clock gear G as it brings one of its pins F under thelever G raises the escapement G (see Fig. 1), so that a pin, like thepin k on the other cams, is released, permitting the cam G to fallagainst the roller E and be rotated.

'This depresses the lever G", the construction of which is the same asthe levers H and operatesthe time-stamp. The construction of this stampis substantially like that of the others, except that, there are twelveteeth upon each of its wheels instead of ten, one of the wheels carryingthe figures 1 to 12, and the other changing by fives so as to print .asshown upon the left side of the chart in Fig. 6. The escapement is ofwellknown form, the pin escaping from the forward tooth and revolvinguntil brought up against the right hand tooth shown in Fig. 1; when thelever Gr drops ofi one of the pins 9 the pin in cam Gr escapes from therear tooth and brings u against the for mechanism with the lever.

wardone, ready for anot er revolution.

An alternative construction is shown in Fig. 7 and in general I preferto use this arrangement.

There the parts are lettered as before, but the roller E is providedwith a rubber .covering 6 and the surface of the cam is roughened so asto make sure of the engagement of the two. In the frame N is pivoted thelever H and a link M, provided with an adjusting sleeve M and lock nut Mconnects the consecutive registering Thisv arrangement takes less powerto operate, there being no cramping ortilting of the registers,

and prevents any risk of the levers getting out of place and failing toregister.

The ribbon, feeding mechanism which I have devised and which is shown inFig. 4 I believe to be new. The ribbon K is carried between the tworeels F F over the stretching rollers F which are shown as. carried uponswinging arms, which may be held open by springs F"; the reels F F? haveratchet teeth oppositely disposed. To the bell-crank F is attached therod F which, asalready described in connection with Fig.

1.,is' reciprocated from the main shaft. Pivoted to the bell-crank F andto a link F, connected to the crank F by a rod F so that the link andbell-crank reciprocate in unison about the centers of the reels F F,are-links F F respectively, connected by rod F.' The pawl F, whichoperates the reel F, and the pawl F operating the reel F, arerespectively carried uponthese links, and pins f f prevent the pawlsdropping too far; as the pawls are to be raised and lowered, the centersof the link F and link F must be different from those of reels F F Acollar F upon the link F receives one end of the pin F and a spring Fbears against the collar so that the pin and the link F constitute thetwo arms of a toggle, kept on one side or the other of the center bymeans of the spring'F;

The operation of this part of the mechanism is as follows: In theillustrated posit ion the bell-crank F carrying with it the llnk F andpawl F is reciprocated by the rise and fall of the rod F ulling over thereel F 4 until the ribbon is all wound off the reel F When the ribbon isdrawn taut so that the reels no longer move, the pawl F begins to climbon the teeth of the reel, carrying with it the link F and putting thespring F under tension until the pawl has passed so far over that thetoggle is forced past the center, when the spring snaps over into thedotted/line position, thus lowering the pawl F and "causing it to engagewith the ratchet on the reel F while the pawl F is raised out ofengagement with reel F The reciprocation of the rod F then causes theribbon to be fed over in the opposite direction until it is all drawnoff the reel F, when the operation is reversed; thus giving a positiveribbon-feed, a1ternating in direction as soon as the ribbon is exhaustedfrom either reel.

Fig. 6 illustrates the form of chart or record'which I prefer, thoughthe apparatus may readily be adapted to other forms. It may be ruled asillustrated, or printed entirely by the apparatus, as may be preferred;in general, however, it should be distinctly separated into columns forthe different machines, soas to leave no room for controversy. The timeis printed on the left; and each of the consecutive registers prints inone of the ruled columns the record corresponding to the machine towhich that register is connected, as will be readily understood withoutfurther description.

It is obvious that with the ordinary forms of consecutive registeringapparatus applied to the purposes of my invention either the numbersmust be so small as to be illegito impair theusefulness of theapparatus. To obviate this I have devised what I believe to be anentirely new form of consecu- .ble, or else the record must be soextensive as 35 sands are shown n Fig. 8, and are of comtive registeringdevice, which prints a line instead of-a unit, and at every tenthimpression prints a number. The principle thus employed is capable, aswill be apparent to those skilled in this art, of further extensionwithout departing from my invention; as for example, it would bepossible to print the line for each ten or one hundred spaces and thenprint a number, or to otherwise vary the relation. lVhen my apparatus isused to keep track of the operations of the engines of a ship during along voyage the printing of the units of revolutions, for example, mightbe unduly cumbersome andunder such conditions a larger multiple might beemployed, or other variation might be made.

The consecutive register which I prefer to use is shown in Figs. 5,5,and 8 to 14. It is provided with an operating handle Lf, having a springZfland. also with guide-pins L L having springs L The spring. Z isweaker than the springs P so that the knob L begins to move before thewhole apparatus, for a purpose presently to be described. The usualunit-wheel in this register is blank; it is shown in Figs. 11 and 12 inside and end elevation, respectively, and marked therein L and isprovided with 2. lug L. Adjacent to it is the unit line-printer L,mounted upon the central shaft of the register by a slot L havingcircular ends; to this line-printer the handle L is secured. The othernumbering wheels or disks corresponding to the tens, hundreds andthoumon construction. As .seen in Fig. 5, pawls L having springs Z holdthe wheels in place ready to print when depressed, and a dog L having aspring Z operates the units-wheel in the ordinary way to change thenumbers, the units-wheel operating the others as usual.

Referring also to Figs. 11 and 12, the units-wheel is shown with a lug Lagainst which abuts the shoulder L of the unitsprinter L, shown in Figs.13 and 14. This looks the two together; but when the lug rotates, theunits-printer may 5 move up and down within the limits fixed by thedimensions of the slot L relative to the figure-wheels of the register.In Figs. 9 and 10 is shown in side and end elevation the yoke L whichcarries the several dogs for actuating the different ratchets of thedevice, one of these being shown at L in Fig. 5.

The operation of this device is as follows:

When the shoulder L and lug L are in 50 the illustrated position, theylock the unitprinter L so that when the lever H is operated the entireregister L is forced down and prints upon the chart the number towhichit happens to be set, together with the line made by the point L ofthe unitprinter. As it rises under the influence or the springs Z Z thedog L throws over the unit ratchet one step, and the lug L is 1'0- tatedout of its illustrated position, shown in Fig. 11 and in dotted lines inFig. 5. It then does not register with the shoulder L of the unitrinterL and the latter is free to move so ar as the slot L" will permit, thespring Z being weaker than the springs Z I. When the lever H is thenoperated it depresses the unit-printer as far as the slot L will permit,bringing it below the face of the type on the numbering wheels andcausing it to print the horizontal line shown on the chart, the springsZ holding the type faces out of engagement with the ribbon K. Thisoperation is repeated ten times; on the tenth stroke the mechanism atthe top of its stroke has returned to the illustrated position shown inFig. 5, except that the next number on the tens wheel has been broughtto the printing position; the shoulder L then locks the parts of thestamp together as before, and when it is depressed the spring Z is notcompressed, the whole power of the lever thus being exerted upon thesprings Z Z so that the whole register prints.
